Title: Improvements in coin-freed vending machines
IPC: G07F11/02
Filed: 1931-07-09
Abstract: 380,193. Coin-freed article delivery apparatus. GILBERT, A., 143, Victoria Park Road, Hackney, and SHERMAN, H., 4, Calverley Street, Mile End, both in London. July 9, 1931, No. 19771. [Class 27.] Coin action, weight. -A coin inserted through a slot 3, Fig. 1, after passing through selector mechanism which may be as described in Specification 372,077 drops to a stop 15 and the tail 43 of a pivoted catch 39 which it tilts by weight. The head 41 of the catch has a number of depressions 45, 47, 49 which engage a camshaped edge 35 on a pivoted goods ejector lever 27, so that the tail of the catch must be fully depressed before the lever 27 can be actuated. This prevents repeated actuation of the lever 27 for one coin insertion. When the lever 27 is fully actuated, the tail 43 can move further and the coin drops to a money-box, the catch 39 returning by gravity. Articles stored in pile.-The lever 27 is pivoted at 29 and is actuated by a knob 7 passing through a curved slot 5. An ejector 19 pivoted at 25 to the lever pushes the bottom article of a pile 11 through a delivery slot 9. The slot 9 is closed by a shutter 10 pivoted to one arm 53 of a bell-crank lever 53, 59 which co-operates with a toe 57 on the ejector lever 27. The toe raises the shutter, when the lever 27 is moved to deliver an article, and holds it closed until a coin is inserted. In a modification, Fig. 4, the ejector lever 127, provided with a knob 107 and coin-freed catch 139 as before, has a bent guard plate 116 which projects through an aperture 114 in the side of the article magazine 113, and on which the bottom article rests. After release, the lever 127 is moved to the left allowing the bottom article to drop to the bottom of the magazine 113 opposite a delivery opening 118 therein, which is now closed by a bar 120 projecting from the lever 127. When the lever is returned to its initial position by a spring 131, the bottom article is pushed through the opening 118 by the plate 116 and drops to a bridge piece 124 adjacent a delivery opening 109.

Patent GB-954526-A (GB)
Title: Paper size and method of sizing paper
IPC: D21H17/54
Filed: 1962-05-24
Abstract: In the production of paper sized with a hydrophobic organic acid anhydride, an aqueous suspension of papermaking fibres or an undried web is treated with an aqueous dispersion of the anhydride (as a solid or liquid) containing a water-soluble cellulose-substantive monomeric or polymeric cationic compound in an amount sufficient to render the anhydride cellulose-substantive.  A large proportion of the sizing properties is thereby developed during the paper drying stage (at a temperature of 190-250 DEG C.).  The anhydride and cationic compound may be added together or separately to the suspension of papermaking fibres.  The anhydride may be added at the beater or stock chest and the cationic agent may be added at the head box. The pH of the papermaking fibres after treatment is preferably 5-8. 0.1-5% of size based on the dry fibres may be employed.  The anhydride may be formed from myristic, palmitic, oleic, stearic, naphthenic, or 1, 12-dodecanedicarboxylic acid, or from a mixture of acetic and stearic acid.  The monomeric cationic compound may be octadecylpyridinium chloride, octadecylamine acetate, N-(2-aminoethyl) stearamide acetate, tetraethylenepentaminestearic acid, stearamidotrimethylene dimethyl 2-hydroxyethyl ammonium dihydrogen phosphate.  The polymeric cationic compound may be polyethylenamine, tetraethylenepentamine-epychlorohydrin, urea-formaldehyde-triethylenetetramine, diethylenetriamineadipic acid-epichlorohydrin, acrylamide-diallyl dimethyl ammonium chloride, casein, glue, acrylamide-acrylic acid treated with alum, or cationic starch.  The polymeric compound preferably has a molecular weight of more than 1,000.  Up to 5% of alum based on the fibres may also be employed.  Polyoxyethylene sorbitol oleate laurate, sodium lignosulphonate, or formaldehyde-naphthalenesulphonic acid may be used as nonionic emulsifying agent.  A dispersion of anhydride and cationic compound may contain 0.5-5% of solid.  Its pH may be 4-6.  A solid dispersion is formed by rapidly cooling a fine emulsion.  The cationic agent may be added before, during, or after emulsification, and before or after cooling.  A dry blend of all the non-aqueous constituents may be formed before emulsification. The blend may comprise a colloid protector, a hydrophobic pigment such as titanium dioxide or ultramarine, and a perfume. Specifications 451,300 and 804,504 are referred to.

Title: Improvements relating to supporting and centering rotary devices, particularly fans of absorption refrigerating machines
IPC: F04D29/04
Filed: 1944-10-17
Abstract: 583,298. Bearings. HOOVER, Ltd. Oct. 17, 1944, Nos. 20037 and 20038. Convention dates, Oct. 21, 1943, and Dec. 31, 1943. [Class 12 (i)] [Also in Group XXXV] An externally driven rotor operating in a sealed fluid-tight system such as the rotor of a circulating gas fan or liquid pump in an absorption refrigerating apparatus is wholly or partly supported by magnetic repulsion and is driven by a rotating magnetic field provided by a moving magnet system or generated by alternating currents. The rotor is also centralized by magnetic repulsion. A hermetically sealed casing 16 welded to the casing 10 of a fan has an outwardly flaring top portion 19 in which is arranged a disc 32 of magnetic material having an inclined peripheral edge. The disc is mounted on a permanent magnet 36 the lower end of which carries a number of pole pieces 40 to which are fixed the fan vanes 44. The fan is driven from an external shaft 20 through a magnetic coupling comprising permanent magnets 30 of like polarity orientation with the internal magnet 36 and depending from a ring 26 of magnetic material carried in a cup-like member 24 on the drive shaft 20, the poles at the lower end of these magnets 30 giving a repulsion drive to the pole pieces 40. The external ring 26 has an inclined section corresponding with the inclined edge of the internal disc 32 and the repulsion effect therefore has vertical and horizontal components, the vertical component taking up the weight of the fan assembly and the horizontal component centralizing the shaft in a stable manner. The internal fan assembly may have a cylindrical shell 45 to form a buoyancy chamber 16 into which inert gas is introduced thereby to take up part of the weight. The permanent magnets are of the materials known under the trade name "Alnico" an alloy of aluminium, nickel, iron and cobalt. The rotary drive may be effected by an induction motor arrangement comprising an external stator fed with alternating currents and an internal rotor, Fig. 3 (not shown), the rotor shaft being supported and centralized at each end by a pair of discs and rings for the two ends of each of the sets of like-orientated opposing permanent magnets which in this form are contained within the sealed casing.
